Shanxi Zhonglian Coalbed Methane Gas Well Liquefaction Project

Hours

30,000 Nm³/day On-Site Liquefaction | A Successful Practice of Non-Pipeline Natural Gas Utilization

Project Overview

  • Location: Shanxi Province, China
  • Liquefaction Capacity: 30,000 Nm³/day
  • Client: Zhonglian Coal, CNOOC, Ningxia Shanglai Energy Co., Ltd.
  • Year: June 2015

Background

The gas wells owned by Zhonglian Coal are located in a remote area with no nearby pipeline infrastructure, making traditional gas recovery methods inefficient and economically unviable. The key challenge for the client was how to commercialize natural gas resources at the early exploration stage.

The client urgently required a solution that could be rapidly deployed, flexibly adapted, and capable of liquefying gas directly at the wellhead to overcome the bottleneck of developing remote gas sources.

Our Solution

KATIANGAS designed and manufactured a mobile natural gas liquefaction unit for Zhonglian Coal. This system features skid-mounted integration, flexible modules, and low energy consumption, enabling on-site gas cooling, liquefaction, and subsequent transportation directly at the wellhead.

The unit was successfully commissioned in June 2015 and has since demonstrated stable operation and excellent performance, earning high recognition from the leadership teams of CNOOC and Zhonglian Coal.

Technical Highlights

  • Mobile Liquefaction Module: Ideal for on-site recovery of unconventional resources like coalbed methane and shale gas
  • Integrated “Extraction-Liquefaction-Transportation” System: Completes the crucial link between exploration and commercialization
  • Highly Integrated Skid-Mounted System: Easy to relocate and deploy, adaptable to various wellhead environments
  • Immediate Compliance and Short Commissioning Period: Greatly reduces the time from construction to gas recovery commercialization

Project Value

  • Successfully achieved stable liquefaction of 30,000 Nm³/day of natural gas, setting a benchmark for non-pipeline natural gas development
  • Enabled the client to commercialize gas sales during the early exploration phase, improving resource conversion efficiency
  • Established a new operational model of “Extraction → Wellhead Liquefaction → End User,” with significant replicable value
  • The project’s experience has served as a reference for the development of multiple remote wellfields
